Y ENVELOPE MACHINE.

Application filed October 7, 19,25. Serial No. 61,127.

This invention relates to envelope machines and more especially tomachines whose object is to receive the paper blank that forms theenvelope and after the side flaps are folded and gummed to join the napswith an eyelet and a cardboard washer, and a gummed protecting rpatchover the eyelet and within the envelope, and during this operation toagiiiX and secure to the closure flap two cardboard washers by means ofmetal eyelets and securing` a string by one of the eyelets, all ofthe-washers being punched with a perforation, cut from an appropriatestrip and located'between the dies that carry the eyelets by plungersworkingl in sequence as the folded blank is fed into the machine andleft under said plungers. rThe strips of cardboard for the washers andthe guinmed paper strip for the pro-V tccting patch are also fed byappropriate mechanismoperating at necessary periods, the incomplet-eenvelopeV beingsuccessively advanced and left at rest until the finaloperation of aiiixingfthe patch, when it is removed to have its bottomflap gummcd and closed to complete it.

These and other'objects and details of the invention., together with themanner of operwion of the machine, are more fully described in. thefollowing specification, set forth in the appended claims, andillustrated in the accompanying drawings, wherein 1Fig, 1 is a verticaltransverse sectional view through the machine on the line 1 1 of il ig.2, and looking towards the front of the saine.

This application for patent may form a part of the machine invented andclaimed by me in application for patent iled August 26, 1921,'Serial No.495,611 and also Patent No. 1,371,270 issued to applica t March 15,1921, for a similar machine whereinthe sides of the envelope are creasedand present invention.

So 'much ofthe pending application Serial No. 195,611 maybe used withthe pre"- ent invention after the clasp forming and ailixing mechanismis eliminated. That is. the present invention is used in connection with.the blank selector' and feed and the `flap creasers and folders, andlocated beyond them and with the herein described is the bottom folderand glimmer that is also shown in the said pending application.

In the accompanying drawings a bed 10 is provided and appropriatelymounted with supporting frames 11 arising from the hed and in which aremounted spindles 12 and 13 respectively carrying al rocking arm 14 and15, oiiset from each other and terminatingabout the center of the bed.

kThe rocking arm 14, as best shown in Fig;

16 while the arm 15 carries an adjacent Both of these plungers 16 and 17carry the die members 18 and 19, respectively, and are actuated by cams2O and 21 whose faces play on rollers 22 in the forked rear ends of therocking arms.

Beneath the plungers and the members and 1 9 are closing :die members 23and the former 'movable through ai passage in the bed l0. The stem 23 ofmember `folded preparatory to the operations of the of the bed a plungeris hollow and through its interior plays independently a needle 26notched at its point to engage a string 27 supplied from any desiredpoint and normally occupying the positions shown in Figs. 1 and 4.

The various moving parts of the machine are actuated from a shaft 28driven from any desired source and having the bevelled gear wheels 29and 30, the forn'ierineshing with a similar wheel 31 on a horizontalshaft 32 beneath the bed 10 and through suitable gearing, such as theworm 33, driving the shaft 311- of the 'cam that at certain perioc selevates a lever 36 connected with the hollow stem 23 to advance theclosing die 23 to its operative position, as shown in Fig. 1.

The shaft 32 through worm gearing 37 also drives a cam 38 that actuatesa lever 39 connected with the lower end of the needle 26 to elevate sameinto position shown in Fig. and through the flap of the envelope.Springs l0 and 41 are provided to retract the levers and needle and dieand at the same time hold the antifriction rollers of the levers againstthe cams.

The gear wheel 3() is at the upper end of the shaft 28 and meshes with asimilar wheel en the horizontal shaft 4t2 journaled in one of the frames11, the said shaft having the bevelled gear wheels 413 that driveidentical wheels on the shafts 414 and 45 journalled in the frames andcarrying the cams 2O and 21 respectively.

Running lengthwise of the bed but supported above it is a tongue 46around which the envelope E is folded and -moved initially by rollers 10while its ends are open and it occupies the position shown in Figs. 1,4t, 6 and 7 when receiving the washers and string.

Through this tongue is a passageway L17 opening on the upper face of thetongue and connected through the nipple L18 and pipe l-Sl with some airexhausting means. The opening` of the passageway is adapted to hold thegummed patch that inserted within the envelope and over the joined sidetlaps while the envelope is moving over it and the patch is cut by vheknife 21) whose vertically moving plunger is operated by the lever 21and the cam wheel 22.

This patch of nioistened gummed paper deposited on the tongue as in theabove described application, Serial No. 495,611 immediately after thecompleted envelope passesv out of the machine, being cut from as stripof gummed paper and moistened as hereinafter described. rlhe knife thenrises and remains elevated until the nextenvelope passes.

As shown in Figs. 4.- and 1l the plunger 21L is operated by the lever 21through the link 21" and plays through the cross bar of frame 11 havingon its lower face a soft rubber cushion 21u whose stem is secured in asocket in the lower end of the plunger, while the lower edge of theknife 20 is on the level with the face of the cushion and cooperateswith a blade 21d. The plunger 21a has two movements as indicated by the'ises on cam 22, the rst movement cutting a patch from the gummed strip97 which drops on the tongue and the second descent of the plunger andcushion on the eyelet F when the envelope reaches that point to securethe patch over the eyelet,

Beneath each plunger 16 and 17 extend the raceways 50, (Figs. 2 and 3)for feeding the eyelets F to their appropriate positions between theclosing dies 23 and 241 and as the latter close, these feeding devices50 are withdrawn leaving one eyelet on the threading needle 26 and theother on the washer beneath plunger 17.

These raceways 50 may be such as commonly used for feeding eyelets wherethey are needed beneath aliixing plungers and are adapted to beretracted after an eyelet has been deposited and as the atlixing plungerdescends to operate on said eyelet. One of the raceways delivers itseyelet over the tongue 16 for the die member 19 to pick it up and tolocate it in the back of the enve- Y lope, while the other racewaydelivers an eyelet beneath the tongue 4:6 and to the needle 26, andafter the delivery of the respective eyelets, the raceways are withdrawnby the usual mechanism commonly employed, until after the dies haveoperated and returned to their inoperative positions and a new envelopeblank put in position for the eyeletting operation.

Figs. 2 and 3 show the raceways in their delivery position while Figs.l, 5 and 6 show the eyelets located and the raceways withdrawn.

The mechanism above described is to affix the washers and string, theformer being of a strong and tough cardboard cut from the strips 51,andl 53 carried on suitable reels 5ft, 55 and 56 at one side of the bedand journalled in trames 52.

One of these strips of paper7 52, `is fed along'the bed 10 and thecompanion strip, 51, over an extension 66 of a cross bar 58, all ofwhich is best shown in Figs. 4A, and 6 and both of the cross bars haveperforations to allow the passage of the respective plungers 16 and 17that play therethrough.

The device for perforating and punching these washers from said stripand returning the washer to the said strip again so that it may beeasily manipulated while carried by the strip to the plungers7 is bestshown in 1, 8 and 9, where it will be seen that the shaft l5 alsocarries a cam 59 to rock a bell crank lever 60 whose longer arm 61carries the plungers 62 and 63.

The plunger 63 has at its lower end a punch 64C adapted to perforate thestrip of Cir paper 51 with each revolution of the cam 59, the wastepassing out of a side passage of the block 66 that forms a part of thecross bar 57.

Through a slot beneath the block or eX- tension 66 the paper strip 52moves, and in a recess 67 in said block and directly beneath the punch64'and its passage is a second punch 68 with a head 69 adapted to beengaged by vertical pins 70 depending from a collar 71 on the plunger 63and at each side thereof and straddling the paper strip 51. Normally thepunch 68 is held in its elevated position by aspring 72 but when theplunger 63 descends it also forces down the punch 68 and causes it toperforate the strip 52 simultaneously with the punching of strip 51, thewaste paper passing .out of the openings 65 and 65.

After the strips have been punched, as shown in Fig. 3, the washers areeut by punches operated by a plunger62, one of them being at the end ofsaid plunger and encircled by the sliding sleeve 7 3, as shown in Figs.`1 and 8, that is pressed downward and awa-y from the collar 74 by thecoil spring 75 and providing a certain amount of lost motion beforeoperating .on a ring 76 to cause it to press againstthe strip 51 bothbefore and after the punch 77 has passed through said strip, and so thatthe lower plunger' 78, normally at the level of the block 66, may followpunch 77 back and replace the washer in the strip while the ring 76 isdepressed and held by sleeve 73.

rlhe ring 76 effects little friction whei'i the plunger 62 is up andlies on the moving paper awaiting the next operation lof plunger' 62.

` rllhe lower end of the plunger 78 comprises la punch 79 for the strip52 and be neath this punch is the plunger 8O normally pressed upward bythe spring 81 in the recess 82 of the bed 10 that is closed at itslowerend by the plate 83. Around the punch 79 is an elevating spring 84and a sleeve 85 that is impinged by pins 86-from the ring 76 and causedto press upon the strip 52 when the strip 51 is compressed by said ring.

The punch 79 also cuts and removes a washer that is immediately returnedto its place in the strip by the returningplunger and the strip isreleased for the nextoperation; Both of the springs 81 and 84 combinedare weaker than the spring 7 5 but strong enough to force the washersback into the respect-ive strips and the ring 76 is free to move up ordown, `.vhile the sleeve moves freely on the punch 79 and both ring andsleeve have slightly bevelled lower faces to allow the strip to passunder them but prevent buckling of the same.

Identical plungers and punches as above described are used for the strip53 that supplies the washers for the die members 16 and 17 `and plungersfor the latter strip are operated bythe arm 61" extending from the hubof thel bell crank lever 1,69.

The strips 51 and 52 are 'given motion and mechanism as abovedescribedpto draw the strip 53 under plunger 17.

In Figs. 1 and 3 it will be seen that the grippers 87 and 88 operate inunison and comprise the slides 93 adapted to recipro cate along the bed10 and the bar 57 while the said gripper 88 operates on a shelf 94 andthe slide carries a depending arm 95 to which the gripper 88 is pivotedto operate on the tableand the latter gripper is connected by theresilient rod 96 with the gripper 87 the spring on the rod being toprovide a yielding `pressure for the member 88.

As the arm 90 is forced outward by the rise in'the cam face, the rod 91rocks the lbell crank lever comprising the jaw 87, so that the lattercatches the paper strip 51 and when the jaw comes to a rest the slide 93is then obliged to move outward on the shelf 94, the arm 95 and the tvvoja'ws, the latter advancing their respective strips.

Tor protect the` interior of the envelope and its lcontents'from injuryby the eyelet after it is affixed by the plunger 17, a strip of gummedpaper 97 is fed over the tongue 46 vwith its gummed side uppermost andmoistened and from the same a patch D is cut to be left on said tongueand held thereon through the suction from passage 47 before the envelopeis placed around the same. This patch D is shown in Figs 4, 5 and 6 andappears as applied to the envelope in the two latter views.

The gummed paper 97 is fed from the left hand side of Figs. 1, 2 and 3(in dotted lines in Fig. 1) by means of a jaw 98 similar Il Y to the jawl87 and comprising a bell crank lever and operated by a rod alsoconnested to the rocking arm -99 on the same shaft and adjacent the arm90.

rl'he operation of the jaw to meisten and v- Y advance the gummed stripis shown in Fig. 10 and is similar to a gummed strip advancer shown inthe above mentioned application Serial No. .495,611 and in this instancethe jaw 98 is pivoted to a sliding tank 97 and carries at its outer enda moistening' wick 98 through which the strip ypasses so it may bemoistened on the gummed or upper side. The forward movement of rod 10()throws the jaw down on a shelf in the tank and .fin 7:1,

llil

meistens and feeds the strip far enough to form a patch. The return ofthe jaw and tank leaves the strip stationary but moistened as far as thetank travels by the wick 98. The tank 97 is adapted to slide on thecross bar 58 being held by bolts passing through a slot.

The string 27 is fed from an appropriate source to beneath a flat spring982 and when the above operations are completed the rollers 101 and 102at the end of the bed and ahead of the envelope, seize the latter andcarry-it forward when the folding bead depresses the bottom flap betweensaid rollers, as described in the aforementioned application Serial No.195,611, to have said `liap sealed and closed. The string 27 also iscarried along a predetermined length and is cut by the blade 103.

It will be seen in Figure t that the roller 102 is mutilated so thatafter being seized, the envelope is allowed to rest during the severaloperations but moved at appropriate intervals and nally carried off bycontinually moving rollers and 111,. i

A second fiat spring 98 is secured to the bed 10 but so as to exert apressure against the bottom of the tongue 16 where it holds the stringafter it is cut as hereafter described. The pressure of the latterspring is less than the spring 982 so that when the needle 26 iselevated, as shown in Fig'. 6, the string is drawn from under the spring98 and its end is passed through the envelope flap and is held there inthe fork of the needle until the plunger 10 descends and meets the diemember 23, depressing the eyelet thereon as the needle is withdrawn. Forconvenience of illustration in the drawings, the springs 982 and 98 areshown parallel with or lateral to the tongues L16.

1n Fig. 5 the string 2T is shown as being forced up in the perforationmade in the flap of the envelope by the needle 26 where it is left andcaught by the eyelet shown on said needle and the washer A on plunger16.

When the latter plunger descends the string is firmly caught by theupset eyelet and the washers A and B and held so that it may besubjected to considerable strain before it can be detached from the flapGr.

The clinching of the eyelet secures the upper washer A from the strip 51to the upper side of the flap while the head of the eyelet secures thelower washer B and. the end of the string 27 is gripped between them, atthe same time gum is applied to the bottom flap.

The above operation is shown in Figs. 4;, 6 and 7, the washer A beingheld over the opening 1n the cross bar 57 until the plunger 16 descendsand carries it through the same opening and also through an opening L16in the tongue 16, after which t-he washer C and its eyelet are securedto the back of the en- Vvelope which with the washers, and stringattached has the gummed patch applied and is carried to the finaloperation of closing the bottom by the rollers 101 and 102. rllhe looseend of the string follows the envelope and the knife 103, playing'through an opening in the bed 10, moves upward and cuts the same afteran appropriate length had followed said envelope. At this operation theenvelope flap has passed the range of the knife and the string 27 againoccupies the position and condition shown in Figs. 5 and 6.

The knife 103 is carried by a plunger 104: that is actuated by a lever105 having a roller 106 playing on the cam 107 carried by the shaft 34:and as the envelope passes out, the string 27 is drawn across the end ofthe needle 26 and left in position to be again caught for the nextoperation.

rEhe raceways 50 with the eyelets are also moved into position so thatthe eyelets may be deposited in the perforations of anew washer C and onthe needle 26, and the latter forces the eyelet through the lower washerand the flap of the new envelope preparatory to having said eyeletclinched.

The envelope is fed into the machine and around the tongue while thesides are closed and sealed but before the bottom is folded and sealed.

Suitable springs are shown to return the parts to their normal positionsand gearing is provided to operate them.

ln Figure 4 it will be seen that while the feed roller 102 iscontinuously driven, it is mutilated so that it fails to feed'after theblade 102 descends and the envelope is advanced far enough to have theplunger 20 affix the gummed patch. The enveloperis then taken up byrollers 101 and 102 again and moved to bring the latter into theinfluenceof rollers 110, and 111, the knife 108 controlled by cuni 107cuts the string to :a predetermined length whiley the envelope is inmotion.

The mechanism connecting' and driving the intermittent envelope feed andthe ad rance of the various strips above mentioned is best shown in Fig.12 where the shaft 34, that also appears in Figs. 1 and L1. is providedwith a worm 122 near its rear end and which nieshes with and drives aworm wheel 123 on the shaft of the roller 110 tha' also carries the gearwheel 12st to drive the gear wheel 125 on the shaft of roller 101. Agear wheel 126 meshes with a larger gear wheel 12T on the shaft of thepaste pot feed 128 and its cams 129 and 130.

By this arrangement the various plungers and strip feeds are operated inunison with the intermittent feedV of the envelope through the machineand the entire operation may be from one source.

After the envelope has been carried olf lll) the tongue 46 theinoistening jaw 98 is advanced, feeding thepgummed patch beneath theplunger 212L Which descends far enough to cause the blade20 to cut oit apatchfthat falls on the tongue being attracted by the air suctionthrough passage 47 and held lirmly on the said tongue before a newenvelope blank is fed over it.

lVhile Fig. 6 shows the practically complete envelope in section, Fig. 7shows the back of saine With the disk A cut from .thestrip 51, thestring 27 and lthe gummed patch at the inside of the back of theenvelope; and the closure is effected by folding down the flap G andclamping the string 27 under the Washer C and about its eyelet F.

As shown in Fig. 4 vafter the envelope passes through rollers 101 and102 it is fed on by rollers and 111 andbetween the cylinders 112 and113, the former adapted to carry a stereotype plate 114 that is inked bythe rollers 115 and makes an impression on the bedding 116 of thecylinder 113, so that any desired printingmay be done on the envelope asit passes through the machine, thus reducing labor where acompleteprinted envelope is desired.l y

The cylinder l113 also carries an adjust-- able bar 117 adapted togather up :paste 'from the roller 118 llocated in the paste pot 119 andVWhen it is Ydesired 4to kalso apply paste to the flap in vaddition tothe string closure. The cylinder 112 may be provided with a flexiblestrip 120 against Whieh'the bar With the flap impinges.
